Patent number: 8551857Abstract: The technique for manufacturing a high-capacitance and high-accuracy MIM electrostatic capacitor by a small number of steps is provided. After a lower electrode of the electrostatic capacitor and second wiring are formed at the same time on a first interlayer insulating film, an opening part is formed in a second interlayer insulating film deposited on the first interlayer insulating film. Next, a capacitance insulating film, a second metal film and a protective metal film are sequentially deposited on the second interlayer insulating film including the interior of the opening part, and the protective metal film, the second metal film and the capacitance insulating film on the second interlayer insulating film are polished and removed by a CMP method, thereby causing the capacitance insulating film, an upper electrode made of the second metal film and the protective metal film to remain in the opening part.Type: GrantFiled: February 25, 2011Date of Patent: October 8, 2013Assignees: Hitachi, Ltd., Asahi Kasei Microdevices CorporationInventors: Yuji Imamura, Tsuyoshi Fujiwara, Toyohiko Kuno

Patent number: 7191874Abstract: The present invention provides a carrying apparatus that prevents an elevating motor and the like from projecting from a stacker crane to hinder the stacker crane from interfering with walls of an automatic warehouse. A traveling vehicle 2 of a stacker crane comprises traveling driving means 20, 20 for wheels 9, and elevation driving means 35 for elevating and lowering a platform 4. Both driving means 20, 35 are arranged so that a longitudinal direction of both driving means 20, 35 is almost parallel with a direction in which the traveling vehicle 2 runs. The traveling vehicle 2 comprises a pair of frames 17, 17 spaced at a predetermined distance from each other and a plurality of connecting members that connect both frames 17, 17 together. Both driving means 20, 35 are arranged outside the respective frames 17. Wheels 9, 9 are arranged in the front and rear, respectively, of the traveling vehicle 2. The traveling driving means 20 is connected to each wheel 9.Type: GrantFiled: August 26, 2003Date of Patent: March 20, 2007Assignee: Murata Kikai Kabushiki KaishaInventors: Akito Tai, Yuji Imamura, Fumiki Goto

Patent number: 5802831Abstract: On a piecing method of a spinning machine which, after cutting a sliver between normally rotating draft rollers and stationary draft rollers, inserts a leading yarn into the spindle of a twist device and carries out piecing by the restarting of the draft rollers, restarting of the twist device and running of the leading yarn, approximately all the fibers comprising the tapered tip of the cut sliver form the joint part by being entangled in the leading yarn. As almost all of the fibers comprising the tapered tip of the cut sliver contribute to the joint part, the success rate of piecing is increased and a stronger joint part may be formed.Type: GrantFiled: May 14, 1997Date of Patent: September 8, 1998Assignee: Murata Kikai Kabushiki KaishaInventor: Yuji Imamura

Patent number: 5704204Abstract: This invention is related to a yarn piecing apparatus of a spinning machine arranged with a holding member (12) that holds the parent yarn (Y') which is inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2), at a predetermined tension so that it does not rotate due to the rotating air current from the nozzle member. As the parent yarn (Y') inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2) is held by the holding member, there is no rotation of the parent yarn (Y') by the rotating air current and consequently, fibers can be reliably attached to the parent yarn (Y') and the success rate of yarn piecing can be increased.Type: GrantFiled: January 3, 1996Date of Patent: January 6, 1998Assignee: Murata Kikai Kabushiki KaishaInventors: Hiroshi Mima, Yuji Imamura

Patent number: 5687143Abstract: A reproducing apparatus for reproducing an information signal from a recording medium in which a recording medium has a modulated information signal recorded thereon by one of different recording systems, includes an optical head for irradiating the recording medium with a light beam, a photoelectric detecting portion for receiving a light beam reflexed from the recording medium and for generating an electric signal as the modulated information signal in response to the received light beam, and a convertor for converting the information signal from the electric signal. The photoelectric detecting portion is arranged to generate the electric signal by different processes in the case where the modulated information signal is recorded on the recording medium by a first system and in the case where the modulated information signal is recorded on the recording medium by a second system different from the first system.Type: GrantFiled: June 15, 1995Date of Patent: November 11, 1997Assignee: Canon Kabushiki KaishaInventors: Koji Takahashi, Yoshitake Nagashima, Yuji Imamura

Patent number: 5673547Abstract: A spinning apparatus having a spinning section for forming yarn by applying a rotating air current of predetermined air pressure to a supplied fiber bundle and twisting the yarn while opening an end of the fiber bundle, and having a piecing section for reverse threading a spun yarn end into that spinning section. The spinning apparatus has a high pressure application member for applying high pressure air at a pressure higher than the aforementioned predetermined air pressure to such fiber bundle during the predetermined time after the spun yarn end is reverse threaded into the spinning section. The high pressure application member includes a first air circuit for supplying the aforementioned predetermined air pressure, a second air circuit that supplies air at a pressure higher than the aforementioned predetermined air pressure and a change-over member between the first and second air circuits.Type: GrantFiled: September 1, 1995Date of Patent: October 7, 1997Assignee: Murata Kikai Kabushiki KaishaInventors: Kenji Baba, Shinichi Satomi, Yuji Imamura

Patent number: 5647197Abstract: A spinning apparatus having a nozzle (n1) that exerts the actions of a rotating air current on the fiber (f), a hollow spindle (s1) and a fiber introduction member (e2) positioned opposite the inlet end part (s1") of the hollow spindle with a fiber guide member (E) arranged with a fiber guiding surface (e9) twisted in the rotation direction of the air flow and the fiber introduction member (e2) projecting from the fiber guide member toward the hollow spindle. The end part of the guide member (E) may be formed into a flat or a curved shape whereby a spun yarn with improved fiber evenness and having higher strength, a round cross section, a better exterior and resembling blend yarn which differs from core yarn, can be spun. Furthermore, improvements in the spinning properties and success rate of yarn piecing can be realized.Type: GrantFiled: December 5, 1995Date of Patent: July 15, 1997Assignee: Murata Kikai Kabushiki KaishaInventor: Yuji Imamura

Patent number: 5585934Abstract: An image signal recording apparatus arranged to be selectively set in a still-image recording mode and a motion-picture recording mode. A storage memory stores on picture portion of the motion-picture video signal. During the still-image recording mode, the content of the storage memory is repetitively read out of the storage memory thereby forming a video signal representing the still-image. The duration of still-image recording mode is longer than a period required to store two picture portions of the motion-picture in the storage memory.Type: GrantFiled: June 7, 1995Date of Patent: December 17, 1996Assignee: Canon Kabushiki KaishaInventors: Katsuji Yoshimura, Koji Takahashi, Yuji Imamura, Kenichi Nagasawa, Yasutomo Suzuki
